This document provides an overview of HTML5, CSS3, jQuery, and REST and how they can be used with SharePoint 2010. It discusses the new elements, functions, and APIs in HTML5 and CSS3 and how they allow for richer user experiences. jQuery is presented as a way to select and manipulate page elements as well as call REST web services. REST services through ListData.svc and returning JSON data are demonstrated. jQuery templates are shown as a way to display data collections. The future of SharePoint development moving more to client-side technologies like these is also discussed.
